Are you ready to upgrade to the Canon EOS 40D from an EOS 30D, or, even, an earlier model like the 20D or 10D? Perhaps you own a Digital Rebel in one of its incarnations, and lust for some of the muscular new features found in the 40D. You might even be a die-hard film camera owner with an earlier EOS model, and lots of EF lenses that will work great on the new Canon 40D. If you fall into any one of these categories, you probably want to know “what’s new?” before you make the jump.
This appendix provides the information you need. I’ve placed it here at the end of the book, rather than as the first chapter because not every reader will need this upgrading advice. In addition, most of the descriptions of features and differences between the 40D and its immediate predecessor the 30D also appear in the main body of the text. I’ve collected all the relevant comparisons and considerations here in one place, where they are readily accessible for those considering an upgrade.
